The invention relates, general to display devices for advertising" and the like and more particularlyto display devices for rotating the article to be displayed.

According to apreferred embodiment, the display .device comprises a dish-shaped base or suppo jth'aving suitable driving mechanism therein. Journalled on the top of this support and driven A plication November 2, 1910;Seriallioitfi ififi' (cl im-3a) 1 clos ne of the invention itmade for pnrp'oses of explanation, but "it w'iil beuri'derstood that the byfsaid mechanism is a turntable or cross member having journalled on its ends resilient wheels engagingthe circular side surface of the base;

'llie shafts upon which these wheels are mounted carrysuitable supportingtrays or holders so that,

as the cr'ossjmember slowly rotates, the resilient wheels roll on the base and slowly rotate the trays or display holders.

' The two holders maybe of the same or different construction. Inone form, one holder may be provided With'clips for holding a bookjin closed 7 condition whilethe other holder may have clips for. holding abook in open condition. If desired, the" driving mechanism may comprise an inexpensive motor of the synchronous clock type, driving su" able reduction gearing driving the turntable. '1 e invention also consists in certain new and V angina features of construction and combination of parts hereinafter set forth and claimed.

Although the novel features which are believed a to be characteristic of this invention will be particularly pointed out in the claims appended hereto, .the invention itself, as to its objects and advantages, and the manner in which it may be carried out, may be better understood by referring to the following description taken in connection with the accompanying drawings forminga part thereof, in which Fig. 1 is anelevation of the display device With parts insection;

The several gears and shafts just described comprise a standard reduction gearing which re-;

duces the comparatively high speed of rotorshaft The closed volume may exhibit the title and indicate the character of the binding of the book, While the open volume will indicate the type of print and also any especially interesting or attractive picture or title page at which point the book will be opened.

As the turntable l3 slowly rotates, the planet wheels [4 and IE will roll upon the sun wheel 25, rotating the platforms 16 and I1 and the books 62 and 63 as indicated in Fig. 4, thus calling attention to the articles displayed and exhibiting them in an attractive manner.

39 to comparatively slow speed of turntable shaft 48. The clock motor and reduction gearing may be such as to impart a speed to shaft 48 of about one revolution per minute. It will be understood, of course,- that, if desired, the mechanism may be arranged to impart any suitableor desirable speed to the turntable,depending upon what type of merchandise is being displayed and what eifect it is desired toachieve.

The turntable shaft 48 is journalled in lower plate 34 and upper plate 36 in the intermediate shafts 43 and 46 are journalled in plates 29 and 36. The plates 36, 29 and 34 may be madeof brass so as not to affect the magnetic circuit of the motor core 25.

The turntable [3 has fixed thereto depending hubs 51 in which are journalled stud shafts 50 to which the wheels 14 and i5 are secured. These wheels may be conveniently made up of a disc 55 of 'rubberor other s'oft'resilient material clamped between dish-shaped discs'54 by nuts 52 threaded on the reduced ends of the shafts 56. The whole I arrangement is such that the soft rubber discs 55 yieldably engage the circularwallil providing, in effect, a frictional planetary gearing system,

the circular wall 2| constituting a sun gear and thewheels [4 audit constituting planet gears."

Each of the rotating platforms l6 and IT carry suitable holding devices for holding the merchandise to be displayed. One end of platform It carries a U-shaped clip '56 suitably secured thereto and the other end of platform l6, which may .be in the form of a bar, is bent to form an upstanding support 51. Platform I! may also be in the form of a bar and may have its one end bent upwardly to form an upstanding support 6| Secured crosswise on platform I! is a crossbar 58 which carries U-shaped clips 59 and 6D.

For displaying books in abook store,for example, a closed boo-k maybe mounted on platform l6. Such a book is indicated by 62 in Figs. 1 and 5. The support52 may be inserted in the space between the binding of the book and the cover surrounding the binding and the U -shaped clip 56 may snugly receive the other edge of the book, thus holding the book substantially rigidly on the platform 16. Another volume of the same book may be supported in open position on the other platform H, the supporting member 6! being. inserted between the binding of the book and the cover loosely surrounding the binding, while one cover and approximately half the pages in the book may be held in one U-clip '59 while the other cover and the other half of the pages are held in the other clip 66. r r

Thus, by the use of the-present inventionya book which it is desired to advertise may be exhibited in an attractive and forceful manner.

. It is obvious that this principle above described may be used for displaying other types it and ll'willbe suitably modified. Fig. 6 indicates platforms 68 and 69 having suitable racks of merchandise in which event the platforms or h ld rslo and ll from which may be hung any desirable articles of merchandise, such as hats, neckties, handkerchiefs, socks, stockings, etc. It is obvious that the display device may be of any size, sufficiently large, for example, to

' display clothing, such as suits or overcoats.

If desired, the holding devices l'fi and H may be omitted and the platforms 68 and 69 may be in the formfof simple trays on which the merchandise may be'placed. The use of trays lends itself very nicely for the display of smaller I articles, such as jewelry, cosmetics, drugs, etc.

Thus, there has been described a simple display device, inexpensive to manufacture and very inexpensive to run in view of thenegligible consumption of electricity by clock motors. There is nothingt'o get out of order, the merchant simply plugs in the electric cord and the deviceis ready town. He places his merchandise on the revolving platforms and no further attention is needed. The planetary rotation of the several holders, or trays has the advantage of displaying the articles equally on all sides as they move before the prospective customer.
